649057e05c Remove forced type changes when they can't deopt 
Hydrogen attempts to force representation changes on certain operations in order
to deoptimise on the change rather than the operation. However, these forced
changes are often unnecessary on 64-bit platforms, and cause poor code
generation, so this patch makes some of them conditional on whether it's
possible for deoptimisation to occur in the change.

On ARM64, this prevents sequences like:
                  ;;; <@46,#89> smi-tag
0x7ff282c7f050   144  lsl x4, x4, #32
                  ;;; <@48,#90> smi-untag
0x7ff282c7f054   148  asr x5, x4, #32
                  ;;; <@50,#31> mul-const-i-s
0x7ff282c7f058   152  lsl w6, w5, #3

918efd7e20 Add non-miss slow path to LoadIC_Normal. 
This avoids endless IC patching cycles between "normal" and "nonexistent" handlers when objects having and not having the property are seen alternatingly
